Big Bear and Lake Arrowhead
Big Bear and Lake Arrowhead are the closest mountain trips from San Bernardino, but the short distance still needs RV-specific planning. Pineknot Campground in San Bernardino National Forest sits near Big Bear Lake at about 6,900 feet, offers tent and RV sites, has no hookups, and can face fire restrictions in hot, dry weather; the dump station is across the lake at Serrano. Check campground fit, fire rules, and Caltrans road or chain controls before sending a large RV up the mountain.
